Description
- This application is a continuation of Serial No. PCT/FR2004/001396, filed Jun. 4, 2004, which claims priority to French Application No. 03/06870, filed Jun. 6, 2003 and French Application No. 03/09157, filed Jul. 25, 2003, all of which are incorporated by reference herein.
- The invention relates to a flexible shaft for transmitting rotary motion, to a rotary motion transmission device including such a flexible shaft, and to an adjustment system for adjusting a motor vehicle seat, which system includes such a device.
- Transmission devices are known that comprise a flexible shaft and a sheath inside which the shaft is received. In particular, the flexible shaft can be formed of one or more core wires made of steel and around which winding wires are wound, the winding wires also being made of steel. In such a transmission device, in particular for adjusting a motor vehicle seat, the speeds of rotation of the flexible shaft in the sheath are higher than 2000 revolutions per minute (r.p.m.), and conventionally about 3000 r.p.m. During rotation at such speeds, vibration of small amplitude appears that propagates along the flexible shaft and that give rise to noise. Trials conducted by the Applicant have shown that one of the causes of the appearance of such vibration is that the elasticity and resilience of the steel core wires used to make the flexible shaft are too high. An object of the invention is to mitigate that problem by proposing a flexible shaft whose core wires present elasticity and resilience that are lower while preserving good strength.
- The Applicant has observed that the function of the core wire is not to transmit the rotary torque, but rather to serve as a support or strength member for the winding wires. Thus, it is possible to reduce the elasticity and resilience of the core wire while preserving the performance of the flexible shaft. Such performance is preserved by means of the good strength of the core wire. Said strength makes it possible to provide a good support for the steel winding wires that transmit the rotary torque. Thus, the combination of a core wire having low elasticity and of winding wires that are elastic makes it possible to obtain a reduction in the vibration phenomenon and also to preserve the performance of the flexible shaft.
- To this end, and in a first aspect, the invention provides a flexible shaft designed to rotate inside a sheath for the purpose of transmitting rotary motion, said shaft comprising at least one core wire and winding wires wound around said core wire, the core wire presenting elasticity and resilience that are lower than the elasticity and resilience of the winding wires. In a second aspect, the invention provides a rotary motion transmission device comprising a sheath and a flexible shaft received inside the sheath, the sheath comprising a core formed of a hollow cylinder whose inside diameter is arranged to enable said shaft to rotate inside said sheath, the flexible shaft being a shaft as described above.
- In a third aspect, the invention provides an adjustment system for adjusting a motor vehicle seat, said system comprising at least one adjustment runner mounted on the structure of the vehicle and adjustable means for fastening the seat to said runner(s), said system further comprising a drive motor provided with at least one rotary outlet, said adjustment system further comprising a transmission device as described above and that is disposed between the outlet of said drive motor and said fastening means, so as to move said fastening means along said adjustment runner in response to said outlet rotating.
- Other objects and advantages of the invention appear from the following description, given with reference to the accompanying drawing, in which:
-
FIG. 1 is a diagrammatic section view of a flexible shaft of the invention, showing the core wire around which the winding wires are wound; -
FIG. 2 is a fragmentary diagrammatic longitudinal section view of a rotary motion transmission device; and -
FIG. 3 is a perspective view of a seat adjustment system of the invention for adjusting a vehicle seat. - With reference to
FIG. 1 , the flexible shaft 1 comprises a core wire 2 around which winding wires 3 are wound. It is also possible to provide a plurality of twisted-together core wires. The core wire 2 is made of annealed copper wire or annealed brass wire presenting low elasticity and resilience characteristics while having good mechanical characteristics such as crush strength and fold strength even after heat treatment at 400° C. that can be applied to obtain the mechanical performance desired for transmitting rotary torque. It is also possible to use other materials presenting elasticity, resilience, and strength characteristics that are similar to those of the annealed brass or copper used for making the core wire 2. In a variant, it is possible to consider using the same material for the core wire 2 and for the winding wires 3. Such a material is subjected to different treatment depending on whether it is for use in a core wire or in a winding wire, so as to obtain the desired elasticity, resilience, and strength characteristics. - The winding wires 3 are steel wires, which makes it possible to impart the desired performance to the flexible shaft 1. For example, said winding wires are disposed such as to form a strip of wires 4 that is wound around the core wire 2. It is possible to consider winding one or more strips 4 around the core wire 2 as a function of the diameter and of the mechanical characteristics that it is desired to impart to the flexible shaft 1. In particular, a plurality of strips 4 can be superposed around the core wire 2.
- Thus, the core wire 2 presents elasticity and resilience lower than the elasticity and resilience of the winding wires 3 while maintaining good strength. As indicated above, the combination of a core wire having low resilience and of winding wires that are elastic makes it possible to reduce the phenomenon of vibration while also preserving the performance of the shaft 1 in terms of transmitting rotary torque. For example, the winding wires 3 are wound helically around the core wire 2. Such a winding generates pieces in relief in the
outside surface 5 of the flexible shaft 1. Such pieces in relief can be removed by machining the flexible shaft 1 so that itsoutside surface 5 is substantially smooth. Such machining makes it possible to reduce further the vibration of the flexible shaft 1 when it is turning at high speed inside a sheath. - With reference to
FIG. 2 , a description follows of atransmission device 6 for transmitting rotary motion and including a flexible shaft 1 as described above. Such adevice 6 for transmitting rotary motion comprises a flexible shaft 1 and asheath 7. The shaft 1 is received in thesheath 7 whose inside diameter is such as to enable the shaft 1 to rotate inside thesheath 7. The speeds of rotation of the core are conventionally about 3000 r.p.m. In order to make such a rotation speed possible, clearance of a few tenths of a millimeter is provided between the flexible shaft 1 and thesheath 7. - In addition, it is possible to provide a lubricant inside the
sheath 7 so as to make it easier for the shaft 1 to rotate inside said sheath. When the shaft 1 is machined so as to present a substantially smooth outsidesurface 5, it is possible to avoid the Archimedes screw phenomenon that gives rise to displacement of the lubricant while the shaft is rotating inside thesheath 7. - The
sheath 7 comprises acore 8 and an outer tubular cladding 9 encasing thecore 8. For example, thecore 8 can be formed of a helical spring made of a metal material. For example, said spring is formed from a helically wound metal strip. The turns of the spring are non-touching, thereby imparting flexibility to thesheath 7. The outer cladding 9 can be made of an extruded plastics material, e.g. polyvinyl chloride (PVC). - The
core 8 of thesheath 7 can be provided with flocking 10 on its inside surface, i.e. on the surface facing the flexible shaft 1. To this end, the inside surface of thecore 8 is coated by any known method, e.g. electrostatically, with flocking 10 that can comprise 6.6 polyamide fibers. It has been observed that such an arrangement in which thesheath 7 is internally flocked presents good sound damping. The flocking 10 makes it possible to guarantee mechanical isolation between the shaft 1 and thesheath 7. In a variant (not shown), the same sound-damping effect can be obtained by using a core wire 2 of low elasticity and of low resilience in a flexible shaft 1 whose outside surface is coated with flocking. - With reference to
FIG. 3 , a description follows of motor vehicleseat adjustment device 11 including a rotarymotion transmission device 6 as defined above. Such anadjustment system 11 includes tworunners runners gears runners - An
electric motor 16 is fastened to the structure of the vehicle or, in a variant, to the framework of the seat. Themotor 16 has tworotary outlets outlets motion transmission devices 6 of the invention to respective ones of thegears motor 16 is powered, it drives the flexible shafts 1 of thetransmission devices 6 in rotation inside theirsheaths 7. The shafts 1 in turn drive thegears runners
